No, you're an idiot, not just telling, and pulling necessary. Although, maybe you're not an idiot, and a spy or partisan. :D But in General, trying new things, the unknown is a normal human trait. Including to jump into the pool without thinking. All you people all you people and nothing clovekove you are not a stranger. :)
How isn't important.
So a new OS just to reinstall the bootloader of Windows. It means that you have to recreate it. Simple edit menu will not do here (I thought the second one Windows installed). Although maybe this Cubase have the opportunity to "virtualize" the already installed Windows? Or, at least, the ability to edit the bootloader. - Lurline commented on June 10th 19 at 14:56

In the BIOS start order need to change

Start BIOS and try to select the first CD-DVD drive, then perezapustit.
If not helped, try it when you start poking buttons F8 or F4 (the display shows which button will start the Recovery) should fall into the category of a failed WIndows boot , and from there choose to CONTINUE with the USUAL START WINDOWS
